Magnetic nanoparticles that are currently explored for various biomedical applications exhibit a high propensity to minimize total surface energy through aggregation. This study introduces a unique, thermoresponsive nanocomposite design demonstrating substantial colloidal stability of superparamagnetic Fe3O4 nanoparticles (SPIONs) due to a surface-immobilized lipid layer. Lipid coating was acco...

in this research, the magnetite nanoparticles (fe304) were prepared by coprecipitation of fe3+ andfe solution in alkaline medium. two kinds of surfactants, cetyl tri methyl ammonium bromide(ctab) and cetyl pyridinum chloride (cpc) were used in the synthesis. fe304 nanoparticles werecoated with human serum albumin (hsa) and bovine serum albumin (bsa). characteristics ofcoated magnetic nanopartic...

In the last decades, nanomaterials and nanotechnologies have become fundamental and irreplaceable in many fields of science and technology. When used in applications, their properties depend on many factors such as size, shape, internal structure and composition. For this, exact knowledge of their structural features is essential when developing fabrication technologies and searching for new ty...

Nanoparticles are known to self-assemble into larger structures through growth processes that typically occur continuously and depend on the uniformity of the individual nanoparticles. Here, we show that inorganic nanoparticles with non-uniform size distributions can spontaneously assemble into uniformly sized supraparticles with core-shell morphologies. This self-limiting growth process is gov...

We describe recent studies on photothermal effects using colloidal nanoparticles. Metal nanoparticles efficiently generate heat in the presence of electromagnetic radiation. This process becomes strongly enhanced under plasmon resonance and also depends on the shape and organization of the nanoparticles. In particular, the amount of generated heat and temperature increase depends on the number ...

Recently, increasing attention has been paid to lecithin/chitosan nanoparticles as colloidal drug delivery system showing the great potential to improve the permeation of encapsulated drug across various biological barriers [1, 2]. However, the overall poor stability of colloidal nanoparticles in an aqueous medium is a significant drawback in their development perspective. Therefore, the aim of...

To resolve handling problem of nanoparticles, due to their small size, a new methodology of electro-spraying and freeze-drying was developed for colloidal nanoparticles of silica and titania to transform them to solid macro-scale nanoparticle assemblies.  The assemblies were then redispersed in an aqueous system to investigate the effect of formulation of original solutions and the process ...

Background: In recent years, silver nanoparticles due to their antimicrobial properties, have formed about 56% of nanoparticles global production. Since the released nanoparticles ultimately enter water ecosystems, their maximum toxic effects are magnified in aquatic ecosystems. The aim of this study is to show how salinity can decrease the toxic effects of silver nanoparticles on exposed rai...

[2] reported that targeted magnetic nanoparticles containing 5-FU can improve the chemotherapeutic effect of 5-FU against hepatocellular carcinoma. Nanoparticles may be defined as colloidal systems (<1 μm), generally ...

Nowadays, hydrogen has attracted significant attention as a next generation clean energy source. Hydrogen is highly flammable, so detection of hydrogen gas is required. Gold nanoparticle based localized surface plasmon resonance (LSPR) is an advanced and powerful sensing technique, which is well known for its high sensitivity to surrounding refractive index change in the local environment. We p...
